1. Social Networking for Research Communities Using Tagging and Shared Bookmarks: a Web 2.0 Application Marlon Pierce, Geoffrey Fox, Joshua Rosen, SiddharthMaini, and JongYoulChoi Community Grids Lab, Indiana University

2. Motivation • MSI-CIEC is an NSF funded project to engage researchers at minority-serving institutions in modern cyberinfrastructure • “Minority Serving Institution-Cyberinfrastructure Empowerment Consortium” • See http://www.msi-ciec.org/eduwiki for more info. • As part of MSI-CIEC, we wanted to pursue social networking and other Web 2.0 approaches. • Enable MSI researchers to find others with similar research interests.

3. Tagging and Social Bookmarking • This was pioneered by sites such as http://del.ico.us • Connotea and CiteULike extend and specialize this for scientific journals. • Idea is to put your bookmarks of interesting URLs on a remote, Web accessible database rather than within your browser. • They can be shared • URLs are tagged with keywords • Everything has an RSS feed • Tags, users, user+tag combos, groups, and so on.

4. Tag Clouds Click-TaggableGrants.gov RSS Feed

5. Click a tag and see all associated links.

6. Sweet Spots for Research Communities? • Most social bookmarking sites have much less profiling and social networking capabilities than Facebook, MySpace, etc. • You can find my bookmarks on del.icio.us but not much else about me. • NSF already has many rich sources of data that can be converted into tags and imported. • Previously funded research: division, directorate, project, investigators, etc. • We also import people and create profiles. • TeraGrid projects and allocations. • RSS feeds of funding opportunities

7. User profiles allow you to describe yourself. Collaborators, awards, and tag profiles are automatically generated.

8. NSF search tags include • Researcher name • Directorate • Award number • Size of award • Year of award • TeraGrid allocation Search NSF Tags to find matches We can span multiple databases with tags.

9. Click Tagging and Grants.gov Feed • There are many useful RSS feeds that we can embed into the portal. • NSF’s “Research Opportunities” feed. • Let’s make it easy to tag these things so you can find collaborators. • Display feeds in the portal • “Interested” and “Uninterested” tags can be assigned in one click. • You can add other tags later. • Why no Grants.gov feed? • Let’s make one with OpenKapow’sRobomaker

10. Your algorithm is displayed above. You can interact with a page Or with the code directly

11. Your RSS feed will be available from OpenKapow.

12. Grants.govrssfeed shown on main page of portal

13. When logged in, click-tags allow you to mark interesting links with a single click

14. Click tag will show any tags that havebeen clicked.

15. Research Opportunities • Social bookmarks create folksonomies. • People, Web site profiles are defined by their associated tags • Users, URLs, and tags define graphs. • Similar to graphs in RDF, OWL based ontologies. • Difference is that these are • NOT predefined, but emerge and evolve from use. • Are suitable for analysis through graph and matrix analysis rather than description logics. • For example, you can build simple recommendation systems using linear algebra • Convert tag graph into matrix. • Find eigenvectors, keep only largest • Calculate dot products for tags. • We are systematically reviewing various techniques for this analysis.

16. More Information • Portal: http://www.msi-ciec.org • Accounts are open • But it would be more useful for us if you give us feedback (bug reports and feature requests). • Email: mpierce@cs.indiana.edu • See me for demonstrations
